FIGS. 4 and 5 are, respectively, a cross-sectional view and a plan viewillustrating an example of a first display portion 110A1 according to anembodiment.

Referring to FIGS. 4 and 5 , the first display portion 110A1 may includea pixel area 31 and the transmission area 32 located adjacent to thepixel area 31 and allowing light to be transmitted through it. The lightmay be external light that is a different light from the light emittedby an emission device EL1 of the first pixel PX1. The external light maybe ambient light or light emitted by the electronic component 30A.

First external light 61 and second external light 62 may be transmittedthrough the transmission area 32. The first external light 61 istransmitted in a direction from the outside of the second substrate 2toward the outside of first substrate 1. The second external light 62 istransmitted in a direction from the outside of the first substrate 1toward the outside of the second substrate 2. Since components andwirings are arranged to bypass the transmission area 32, the componentsand wirings may not be arranged in the transmission area 32. Thetransmission area 32 may not be provided with at least a fourthinsulating film 15. An insulating film provided in the transmission area32 may include a transparent insulating material.

The pixel area 31 may include an emission area 312 and a circuit area311. The first pixel PX1 may be arranged in the pixel area 31. Theemission device EL1 of the first pixel PX1 may be arranged in theemission area 312. A pixel circuit of the first pixel PX1, which iselectrically connected to the emission device EL1 and includes a thinfilm transistor TR1, may be provided in the circuit area 311. Thecircuit area 311 and the emission area 312 are not overlapped with eachother, and thus the emission device EL1 and the pixel circuit may bearranged close to each other not to overlap each other. The presentdisclosure is not limited to a case in which one thin film transistorTR1 is provided in the circuit area 311 illustrated in the drawing, anda plurality of thin film transistors and capacitors may be furtherincluded, and wirings such as scan lines, data lines, and power linesconnected to the thin film transistors and capacitors may be furtherincluded.

The thin film transistor TR1 may include a semiconductor layer 111, agate electrode 112, a source electrode 113, and a drain electrode 114,on a buffer layer 11. A first insulating film 12 between thesemiconductor layer 111 and the gate electrode 112 may function as agate insulating film, and a second insulating film 13 between the gateelectrode 112, and the source electrode 113 and the drain electrode 114may function as an interlayer insulating film.

The emission device EL1 may include a first electrode 116 on a thirdinsulating film 14 that covers the thin film transistor TR1, a secondelectrode 130 facing the first electrode 116, and an intermediate layer117 between the first electrode 116 and the second electrode 130. Atleast one edge of the first electrode 116 may be covered by the fourthinsulating film 15. The emission device EL1 may be of a top emissiontype or a bottom emission type.

The first pixel PX1 may be, for example, a first red pixel Pr, a firstgreen pixel Pg, or a first blue pixel Pb. The transmission areas 32located adjacent to the first pixels PX1 may be connected to oneanother, forming a common transmission area. In this case, since thearea of the transmission area 32 is increased, transmittance of thefirst display portion 110A1 may be increased. In the embodiment of FIG.5 , the transmission areas 32 located adjacent to the three first pixelsPX1, for example, the first red pixel Pr, the first green pixel Pg, andthe first blue pixel Pb, are connected to one another, forming a singletransmission area.

FIGS. 6 and 7 are, respectively, a cross-sectional view and a plan viewillustrating an example of a first display portion 110A2 according toanother embodiment.

Unlike the first display portion 110A1 illustrated in FIGS. 4 and 5 , inthe first display portion 110A2 illustrated in FIGS. 6 and 7 , thecircuit area 311 and the emission area 312, which are included in thepixel area 31, are overlapped with each other. The transmission areas 32located adjacent to the first red pixel Pr, the first green pixel Pg,and the first blue pixel Pb may be connected to one another, forming asingle common transmission area. In this case, compared to theembodiment of FIGS. 4 and 5 , the area of the transmission area 32 maybe further increased. The emission device EL1 may be of a top emissiontype. Since the respective elements are the same as or similar to thoseof the embodiment of FIGS. 4 and 5 in terms of function, detaileddescriptions thereof are omitted.

When the first display portion 110A1 (or 110A2) is in the transparentmode in which light is transmitted, the transmittance control component20A may be in the transparent state, and the first external light 61 andthe second external light 62 may be transmitted through the transmissionarea 32 of the first display portion 110A1 (110A2). Accordingly, thefirst display portion 110A1 (110A2) is in the transparent state.Accordingly, the user located outside the first substrate 1 may observean object located outside the second substrate 2 from the first externallight 61, and the user located outside the second substrate 2 mayobserve an object located outside the first substrate 1 from the secondexternal light 62.

When the first display portion 110A1 (110A2) is in a black mode in whichno light is transmitted, the transmittance control component 20A is inthe opaque state, and the first external light 61 and the secondexternal light 62 may not be transmitted through the transmission area32 of the first display portion 110A1 (110A2). Accordingly, the firstdisplay portion 110A1 (110A2) is in the opaque state. Accordingly, theuser located outside the first substrate 1 may not observe an objectlocated outside the second substrate 2, and the user located outside thesecond substrate 2 may not observe an object located outside the firstsubstrate 1. Since the first display portion 110A1 (110A2) is in theopaque state, an image displayed on the first display portion 110A1(110A2) may be excellent in producing a black color.

FIG. 8 is a cross-sectional view of an example of the second displayportion 120A according to an embodiment.

Referring to FIG. 8 , the second display portion 120A may include anemission area 41 and a non-emission area 42 around the emission area 41.Components and/or wirings may be arranged in the non-emission area 42,and no external light is transmitted through the non-emission area 42.

A pixel circuit of the second pixel PX2 that is electrically connectedto the emission device EL2 and includes a thin film transistor TR2 maybe provided in the non-emission area 42. In another embodiment, a partof the pixel circuit is provided in the emission area 41, and thus theemission device EL2 and the part of the pixel circuit may be overlappedwith each other. Although only one thin film transistor TR2 isillustrated, the present disclosure is not limited thereto, and thepixel circuit may further include a plurality of thin film transistorsand capacitors, and also wirings such as scan lines, data lines, andpower lines connected to the thin film transistors and capacitors.

The thin film transistor TR2 may include, on the buffer layer 11, asemiconductor layer 121, a gate electrode 122, a source electrode 123,and a drain electrode 124. The first insulating film 12 between thesemiconductor layer 121 and the gate electrode 122 may function as agate insulating film, and the second insulating film 13 between the gateelectrode 122, and the source electrode 123 and the drain electrode 124may function as an interlayer insulating film.

The emission device EL2 may include the first electrode 126 on the thirdinsulating film 14 that covers the thin film transistor TR2, the secondelectrode 130 facing the first electrode 126, and an intermediate layer127 between the first electrode 126 and the second electrode 130. Anedge of the first electrode 126 may be covered by the fourth insulatingfilm 15. The emission device EL2 may be of a top emission type or abottom emission type. When the emission device EL2 and the pixel circuitare not overlapped with each other, the emission device EL2 may performtop emission or bottom emission. When at least a part of the pixelcircuit is overlapped with the emission device EL2, the emission deviceEL2 may perform top emission.

The second pixel PX2 may be, for example, a second red pixel Pr, asecond green pixel Pg, or a second blue pixel Pb.

The third substrate 3 may include at least one transparent materialsuch as glass, silicon, synthetic resin, and/or aerogel. In the presentembodiment, an overall thickness of a display apparatus may be reducedbecause one substrate of the transmittance control component 20A (20B)and one substrate of the display panel 10A (10B) are shared together.

The transmittance control layer TM may include a light absorbingmaterial or a light blocking material. The transmittance control layerTM may include coloring suspended particles in an organic solvent andgel, an electrochromic material having transmittance that is changed byelectric oxidation/reduction, liquid crystal and/or dyes having a phasethat is changed by a voltage, and/or black ink having transmittance thatis controlled according to a movement state by a voltage. Thetransmittance control layer TM may change transmittance through a statechange, phase change, and/or position change of a material between thefirst substrate 1 and the third substrate 3.

The transmittance control component 20A (20B) is not limited to theabove-described embodiment, and may be implemented in various forms.Furthermore, the transmittance control layer TM is not limited to theabove-described embodiment. For example, the transmittance control layerTM may be a physical optical element that is controlled to block ortransmit light between two substrates by an electromagnetic field, suchas a liquid crystal layer.

Although not illustrated, when the electronic component 30A (30B) is animage sensor, a lens may be provided between the transmittance controlcomponent 20A (20B) and the image sensor.

The display apparatus according to the above-described embodiments maybe implemented in mobile phones, smart phones, notebook computers,terminals for digital broadcast, personal digital assistants (PDA),portable multimedia players (PMP), or navigation devices.

Although in the display apparatus according to the above-describedembodiments, the transmission area transmits light, the embodiments ofthe present disclosure are not limited thereto. For example, thetransmission area of the display apparatus may transmit signals such assound or waves with a frequency other than that of light, and theelectronic component may include a speaker, a microphone, or an antenna.

When an electronic component is provided by using a penetration portionthat penetrates a non-display area around the display portion or a partof the display portion, the non-display area and the penetration portionare seen by the user. As the number of the provided electroniccomponents increases, the non-display area and the penetration portionincrease, and thus the area of the display portion decreases. Incontrast, in the display apparatus according to embodiment of thepresent disclosure, at least a part of the display portion isimplemented by a display portion having a transmission area, and theelectronic component is arranged corresponding to the transmission area,and thus a full screen display without a non-display area such as abezel area or the penetration portion is available while having variouselectronic components.

Furthermore, in the display apparatus according to embodiments of thepresent disclosure, the transmittance control component is providedbetween the display portion having a transmission area and theelectronic component, and during driving of an electronic component,displaying an image and observing an external object may be possiblethrough the light transmission of the transmittance control component.Furthermore, as the light transmission of the transmittance controlcomponent is prevented during non-driving of the electronic component,the display portion having a transmission area may be able to produce ablack color, and the electronic component may be prevented from beingseen during displaying an image.

As described above, according to various embodiments of the presentdisclosure, since the display apparatus includes, in the displayportion, the transmission area corresponding to an area where anelectronic component such as a sensor is provided, various electroniccomponents are provided and simultaneously full screen display ispossible.
